Hello guys! I want to present before you an awesome tool StopStalk to keep track of your friends' submissions on various competitive websites(Codeforces, UVa, Timus, Codechef, Spoj, HackerEarth, HackerRank).

And that is just not it. It has a lot of other features —

Streak notifier of your friends

Feel like solving algorithmic problems — Why go to Codeforces and search for a problem? Solve problems from across all the platforms. Search a problem by tag. See which friends have solved that problem and what is the difficulty level of the problem.

Want to solve problems that other coders are solving recently - We got a list of trending problems both globally and also amongst your friends.

A global leaderboard along with a unique rating which includes submissions from all the websites.

Do you forget contests? — We got a list of upcoming contests and an option to remind you 30 mins before the contest starts.

Do you often remember some friend's submission on a particular site and want to view that submission — We got you covered. We have a filter page to find exactly what you want.

If you add a custom friend only you can see his/her submissions. This is useful when one of your friend is not on StopStalk or not accepting your friend request! Though the better method will be to invite him/her on StopStalk. And a lot more!!!

The goal is to keep people motivated in algorithmic programming and solve more and more problems. And yeah we do have a referral program. Just share your StopStalk handle after registering with your friends and ask them to enter while registering.

Also you get these awesome Laptop Stickers for just making friends. Increase your network of friends and enjoy its perks. Stickers will be dispatched on 11th April.

Great work man. I found this tool to be really useful, especially the contest reminder. I often intend to write contests but then forget about them as the day goes on. Also, the fact I can see all future contests from all platforms also helps a lot in deciding which ones to write.

Register now if you still haven't seen the awesomeness — https://www.stopstalk.com If you already have, start adding more and more friends by sending friend requests, or custom users or by inviting them to register on StopStalk. Believe me, if you are an Algorithmic Coder(Or a wannabe) you won't regret registering at all!

Hey @code_astra ! Thanks man. We are planning to add TopCoder, but since we do not have a global submissions page for each user, it is not an easier task. We are looking forward to talk to TopCoder team if they can provide the submissions in an easier fashion. If you know the URLs where the user submissions are found please help us through that. Either comment here or on Github issue ! Similarly keep pouring in such valuable inputs in the future :)

Great tool for tracking practice progress.Thank you. Some personal advices: 1.Add tracking for more online judges, like UVa, POJ, HDU, etc.(maybe vjudge.net will be a great reference). 2.Tracking for TopCoder practice (this will be a little bit hard). 3.Anti-cheat and filter out bots. 4.Some problems may appear on various sites, It will be good to merge them into one.This will bring us a great convenience and make that site a hub for full tracking. Hope your great tool be greater.

We have certainly laid out a plan for UVa (and will be rolling out minor updates soon for getting the handles) and soon will be adding it completely as any other Profile Site. We will surely consider LightOJ and will send a survey form and accordingly decide :)

We will send a personal email about these updates (Make sure you and your friends have registered) :)

Also its been some time since we have asked you guys about your views/feedback on StopStalk. It was really helpful the last time and we have tried to address all the issues. Please take a few minutes to fill out this new Survey Form.

Hey @mandavadesik1, it worked yesterday also. It might be possible that it might be down for around 2-3 minutes due to excessive traffic via CodeForces. We are not exactly sure about which previous you are talking, the site is still the same :) For more queries write to us at https://www.stopstalk.com/contact_us . Thank you for your immediate reporting of the error.

Hey @MauricioC, We use a standard API to validate emails. This is to block the users who register from temporary emails. Please write to us at https://www.stopstalk.com/contact_us/ if you have a valid email ID and we will help you out from there :)

Hey majk, we have added your Institute :) At present we don't have that in our roadmap but do let us know here with some details like does it have a public submissions page given a user handle and we will definitely look into the possibilities.

Hey fiter, It's not just about stalking, we definitely started with just that as the end goal but we have evolved to a tremendous frontier of user analytics that can be used to improve exactly where we need to. Stalking on StopStalk is not just stalking but also a sense of hope that you will also become like your friend if you follow a similar path. If your friends are not that great competitive programming then you can always follow any of the great coders and see how they progressed :)

Yeah, you can follow the similar path... But it doesn't mean that this path will take you to the place where it did take it's owner... People can walking similar paths but the outcome will be different

Thanks for your response fiter. Considering these inputs constructively, we'd like to express a few things.

Generally speaking, the paths (or say, trajectories) set by even a few of our acclaimed acquaintances might help us in making informed decisions in myriad spheres of our lives. These associative social influences are eventuated implicitly, thus consequentially being intermediate conduits significantly responsible for individual growth. Not diving much into the sociological aspects, it's safe to conclude that it depends on how one would like to construe the anatomy of social influences.

We at StopStalk keep striving towards identifying these interactions, thus paving way for increased collective growth. If you may, do register at StopStalk and find it out yourself how things are structured to serve the proclaimed mission :)

Hey shahidul_brur, We understand you want to view submissions filtered tag wise for every user. That is indeed a great idea since now we have clustered problems based on various tags into one single category of problems. We will surely add this feature and let you know. Thank you for your input.

As many of you guys requested about the ambiguity of the icons in the navbar — we have cleared the icon clutter from the navbar — Video

We have added a small button on the leaderboard page as well as on the user profile page to view the list of custom users by a user. What you can do with that is you can simply add them to your custom user list ;) — saves you from the pain of entering the handles again.

We have reached 5100+ users from universities across the world (Last year we were 1500 at this time)

Thank you guys for your love and support, we will keep on doing the great work and build a tool with all the features that you want :)

Most awaited feature is here! — Now you can instantly submit a request to retrieve your submissions across all the profile sites on StopStalk with a button click and we will get you your submissions in 5 minutes (max) instead of 24 hours ;)

We have created a group "StopStalk Community". If you're a competitive programmer — join us and let's learn from each other. We can discuss features on StopStalk too and get other people's views on them :)
